Hello.I am using a GSM modem ( model : SIM100T) and I am using AT commands for communicate to my modem.If I use ( AT+CNMI=? ) command then my modem answer ( +CNMI: (0-3),(0-3),(0,2),(0-1),(0-1) ) BUT I want to store Status Report into SIM card.I know that the 4th parameter of AT+CNMI command must be set to value "2" and not "1" but it is impossible. also, my modem don't accept ( AT+CPMS="SR") command because If I use ( AT+CPMS=? ) command, then my modem answer ( +CPMS: ("SM"),("SM"),("SM") ).Does my modem not support them or the problem is another thing that I don't know it
